About 40% of the components of the C-919 comes from abroad. How long does it take before China can replace them. Are there any efforts underway to replace them. Because these days exports bans can happen with just a stroke of a pen.

Most of the foreign components were included through public bidding. On this list, most of the foreign components have domestic counterparts. I'm sure there was also some behind the scenes negotiations to purposely include foreign suppliers in order to pave the way for FAA and EASA approvals. The only real showstopper is the engine. The reason there isn't already C919 options for things like the landing gear and tires is because COMAC took the path of least resistance. This is the general trend of development that most of China's high tech projects take. They accelerate development by taking the lowest cost, fastest approach to realize project goals. Then, once the integrated platform is certified, they move towards greater indigenization. This is the general development trend worldwide nowadays. It's only in China's case where analysts focus so much on the indigenous content because it's under such constant sanctions threat, as you suggested.

60 percent parts are now produce in mainland. its now official confirmation. that's huge considering China started just a decade ago in civil aviation.

by 2025, COMAC planning to produce 90 percent parts. almost entire C919 domestically. i have post many times on this thread.

based on this supply chain, COMAC will build CR929. i heard many encouraging news about this wide body aircraft. this plane will carry highest number of domestic parts.

engine , nacelle , APU , high end nuts , bolts will be done by 2025.

this is domestically made complete package. engine + nacelle. i didn't know that, nacelle is the hardest part in civil aircraft to produce. only few firms in the world are capable to produce. but China conquered this too.

60% is already damn good in airliner manufacturing, which builds on decades of real-world experiences. I would be very happy if C919 is selling at the same level as Airbus and Boeing in China in the next 20 years. WS10 was the most difficult huddle. WS10 is already a success story. So I totally expect China produces domestic high-bypass turbo-fan engines at a similar level of US/UK/France in the next 20 years. By the time C919 can compete with A321neo on the same commercial terms, China would be the strongest manufacturing superpower, on top of what China is today - the largest manufacturing power.

Dreamliner is 70% domestic so yeah, China's 60% is very impressive

i think after USA, China is only second country to actually produce 60 percent parts of a narrow body aircraft. coz Airbus supply chain spread across global include USA/Japan. France/UK don't produce components that much.

France in high bypass turbofan engine is heavily dependent on General electrics. all projects are joint venture.

UK don't do component manufacturing anymore. just design , assemble and testing. except outer body , front fan and maybe some cold components.

Trent XMB supply chain list. LOOOOOL

right now only USA, Russia and China producing high bypass engines entirely with local supply chain.

by 2030, China will be leading player in aero engine tech globally along with the USA and UK ..

Yeah, what is the source for 60%? And what does domestically mean, it is only Chinese companies, or foreign also who produce the parts in China?

and 60 percent localization means include foreign firms, parts produce in mainland with local firms in collaboration.
